Who's altering display? (4)

Ross

I believe the answer is:

show

'display?' is the definition.
(I know that display is a kind of show)

'who's altering' is the wordplay.
'altering' is an anagram indicator.
'whos' with letters rearranged gives 'SHOW'.

(Other definitions for show that I've seen before include "Expose" , "charade" , "Exhibit - present" , "Labour's evidence for starting" , "Demonstrate - parade" .)
